Cov Txheej Txheem Ua Txheej Txheem Ntawm Cov Hnyav iav Fwj

Cov txheej txheem tsim cov naj hoom iav fwj muaj xws li: seasoning, melting, forming, quenching thiab lwm yam txheej txheem. Txhua cov lus hauv qab no:

1. Lub caij nyoog, raws li cov ntawv teev npe ntawm cov phiaj xwm tsim, nyhav rau ntawm ntau cov ntaub ntawv nyoos thiab sib xyaw lawv tus tov. Cov ntaub ntawv nyoos ntawm laminated iav yog: quartz xuab zeb, dolomite, marble, ammonium bicarbonate, boric acid tov thiab lwm yam.

2. Rau melting, cov khoom siv raug xaiv tau muab rhaub hauv qhov kub thiab txias kom ua cov kua nyeem ntawv zoo hauv cov kua iav tsis muaj npuas. Qhov no yog qhov nyuaj heev tag nrho cov txheej txheem ntawm kev hloov lub cev thiab tshuaj. Cov yaj ntawm cov iav laminated yog nqa tawm hauv qhov cub tawg. Muaj ob hom tseem ceeb ntawm kev ua kom sov lub cub taws: ib qho yog cov nplaig tong kiln, laminated iav frit muaj nyob hauv lub lauj kaub tong thiab rhaub nyob sab nraud ntawm lub lauj kaub tong. Lub qhov cub me me lub qhov cub tsuas yog tso ib lub lauj kaub rau hau, thiab lub qhov loj loj tuaj yeem muaj ntau txog 20 tong huam. Lub nplaig lauj kaub kiln yog tsim nyob rau hauv qhov sib txawv, thiab tam sim no tsuas yog cov tsom iav qhov muag thiab lub suab nrov laminated iav yog tsim hauv qhov cub ci lauj kaub kiln. Lwm qhov yog lub taub roj tank, qhov uas lub laminated iav frit yog yaj hauv qhov cub, thiab hluav taws yog siv los ua cua sov lub siab kawg ntawm lub laminated iav kua theem. Lub sijhawm ua haujlwm kub yaj ntawm laminated iav feem ntau 1300 ~ 1600 ° C. Feem ntau ntawm lawv yog kho kom sov nrog cov nplaim taws, tab sis kuj muaj qee qhov cua sov nrog hluav taws xob tam sim no, uas yog hu ua hluav taws xob melting rauv.

3. Txoj kev ua yog los hloov lub molten laminated iav mus rau hauv cov khoom ruaj khov nrog cov khoom zoo. Kev txhaj tshuaj yuav tsum tau nqa tawm nyob rau hauv qee qhov ntsuas kub. Nov yog tag nrho cov txheej txheem ntawm tub yees. Cov iav laminated ua ntej pauv los ntawm cov kua dej khov mus rau lub xeev yas, thiab tom qab ntawd mus rau hauv cov khoom siv ua kom dej khov. Cov txheej txheem moulding tuaj yeem muab faib ua ob hom: phau ntawv molding thiab kev siv tshuab moulding.
